Why is dengue fever on the rise?

Why is dengue fever on the rise?

As one of the “neglected” tropical diseases, dengue is affecting substantially increasing number of people and proportion of global population due to factors including globalization, human settlement, and possibly climate change.

Is dengue fever on the rise?

Dengue is the most common and fastest-spreading mosquito-borne virus in the world. In fact, there has been a 30-fold global increase in the incidence of dengue in the past 50 years,6 with an estimated 50 million dengue infections now occurring each year.

When is dengue peak season?

The peak of the dengue epidemic period is around June to August during the rainy season. It is believed that climate is an important factor for dengue transmission.

What is the future of dengue?

Globally we predict 2.25 (1.27–2.80) billion more people will be at risk of dengue in 2080 compared to 2015, bringing the total population at risk to over 6.1 (4.7–6.9) billion (Table 2), or 60% of the world’s population, according to RCP6.

How much platelets increase per day?

Typical dosing for an adult is a pool of 6 whole blood derived (sometimes referred to as random donor) platelets or one apheresis platelet. This is expected to raise the platelet count by 30,000-60,000/uL in a 70 kg patient.

Is 1 lakh platelet count normal?

The normal count of platelets is 1.5 lakh to 4.5 lakh per microlitre of blood. In viral fever, it reduces up to 90,000 to one lakh. In dengue, this count goes down to 20,000 or even lower, but reaches the normal once dengue is cured. In a viral fever this count comes to the normal range gradually.”

Can dengue spread man to man?

An infected mosquito can later transmit that virus to healthy people by biting them. Dengue cannot be spread directly from one person to another, and mosquitoes are necessary for transmission of the dengue virus.

Why there is no cure for dengue?

A vaccine will not be as simple as one for measles or mumps: Dengue is caused by four related but entirely individual viruses (dengue 1 to 4), which differ in their antigenicity, meaning that any vaccine you develop must protect against not 1 virus, but 4.

What are the symptoms of dengue hemorrhagic fever (DHF)?

Dengue virus infection may remain asymptomatic or manifest as nonspecific viral infection to life threatening dengue hemorrhagic fever (DHF)/dengue shock syndrome (DSS). Patients with DHF/DSS have fever, hemorrhagic manifestations along with thrombocytopenia and hemoconcentration. Thrombocytopenia a …

What are the symptoms of classic dengue?

Dengue Classic dengue fever, or “break bone fever,” is characterized by acute onset of high fever 3–14 days after the bite of an infected mosquito. Symptoms include frontal headache, retro-orbital pain, myalgias, arthralgias, hemorrhagic manifestations, rash, and low white blood cell count.

What is the prognosis of dengue without DHF?

Studies from different countries have reported life-threatening complications from dengue in the absence of one or more of the current criteria for DHF. Despite the name, the critical feature that distinguishes DHF from dengue fever is not hemorrhaging, but rather plasma leakage resulting from increased vascular permeability.

How do you treat dengue fever?

Treatment of dengue fever emphasizes • Relieving symptoms of pain. • Controlling fever. • Telling patients to avoid aspirin and other nonsteroidal, anti-inflammatory medications because they may increase the risk for hemorrhage. • Reminding patients to drink more fluids, especially when they have a high fever. 2 |Dengue and Dengue Hemorrhagic Fever
